Installation and Operation Manual (REV H) PVI 6500 / PVI 7500 1 Introduction The PVI 6500 and PVI 7500 are single phase, grid‐tied PV inverters designed to be interconnected to the electric utility grid. By following the instructions in this manual, the PVI 6500 ‐ PVI 7500 can be installed and operated safely. This installation guide is to be used as reference for commissioning and as a guideline on how to use the inverter most effectively. Feeding power onto the grid involves conversion of the DC‐voltage from the PV‐array to grid compatible AC‐voltage by “inverting” DC to AC. This unit feeds power into a standard 240 VAC split phase electrical system or two phases of a 208 VAC, 3‐ phase commercial, industrial or institutional facility’s electrical system that is connected to the electric utility grid. The inverter can also be connected to one phase and neutral of a 277 VAC electrical service. If the PV system and inverter are providing the same amount of electrical power that the facility is using, no power is taken from or fed onto the utility grid. If the facility is using more power than the PV system is providing, then the utility grid provides the balance of power. If the facility is using less power than the PV system is generating, the excess is fed into the utility grid. Be sure to look into local regulations regarding net metering and interconnection in your local area. Note that some utilities need to change their revenue kWh meter to a bi‐directional type for proper net metering measurement or incentives/billing. Photovoltaic ...

AC Voltage: The PVI 6500‐7500 inverters are 240V AC grid connected devices. They are also suitable for 208V and 277V AC grid‐connected use. For example, connection between two phases of a 208V AC, 3‐phase service or connection between one phase and neutral of a 277V AC service (where acceptable by code). No unit (PVI 6500 or 7500) can be used with a 120V AC service. The units are factory pre‐set to auto‐detect 277VAC, 240VAC or 208VAC when connected with a neutral. They can also be configured for either 240 or 208 VAC without a neutral at the factory or by a qualified installer. Use with 277VAC must always use a neutral as the neutral is used as a current carrying conductor. WARNING: The inverter should not be opened at any time unless authorized by Solectria. The unit is sealed at the factory and its UL listing will no longer be valid and the warranty will be void if opened or tampered with in any way. Multiple Units: Multiple PVI 6500‐7500 units can be used at the same location as long as all electrical codes, local building codes and area utility guidelines are followed. If multiple units are used, each inverter must have its own dedicated AC over current protection device, and PV strings cannot be wired to multiple inverters. ...

The PVI 6500‐7500 is fitted with a self‐diagnostic system, which can recognize the majority of possible faults and show these on the display. This allows the operator to rapidly identify possible problems in the solar inverter or PV system. Please refer to the LCD section (4) for a thorough explanation of fault codes, modes, etc. Ground Fault: If a significant ground fault occurs in the PV array or wiring, the GFDI fuse (located in the wiring box) may be blown. If it is, locate and repair the ground fault and only then replace the fuse with Bussmann KLKD1 (1 Amp, 600VDC). Call the Solectria Renewables customer service hotline for assistance with locating a DC ground fault in the array or conduits. If the GFDI detects a ground fault, the Ground Fault LED will light and the “fault” will be displayed. Weak Sunlight Condition: Operation in weak sunlight, (for example early in the morning, when overcast or when snow is covering most or all of the PV array) can cause the inverter to go through a cycle of trying to start and restart several times. This can occur if the array reaches 260V (strike voltage) but there is nearly no power available. ...

Installation and Operation Manual (REV H) PVI 6500 / PVI 7500 WARNING! For continued protection against risk of fire, replace only with the same type and ratings of fuse (600 VDC, 1A)! Replacing the PV String Fuses The inverter is shipped with five (5) 15A, 600Vdc PV string fuses for PV strings. However, the size of the PV string fuse is determined by the electrical ratings of the PV module and by UL and code requirements. The minimum size of the PV string fuse is calculated using the short circuit current rating (Isc) of the PV module. Please be sure to consult with the PV module manufacturer for appropriate PV string fuse rating. IN NO CASE SHALL FUSES OF LARGER THAN 20A BE USED IN THE PV STRING ...
PV arrays are always energized when exposed to light therefore hazardous voltage is still present on the terminal blocks and the PV string fuse holders even when the DC/AC disconnect switch is switched OFF. Please cover the PV arrays with opaque materials during PV string fuse replacement. CAUTION! The string fuse size must not be greater than the maximum fuse size rating of the PV module provided on the PV module manufacturer data sheet. If no maximum fuse size is indicated, please contact the PV module manufacturer. 5.4 Factory Service Please contact Solectria Renewables customer service hotline for our documentation on removing and replacing the top inverter section (while leaving wiring box in place). 5.5 Inverter Replacement Once the product is diagnosed and Solectria determines that it requires Factory Service, the product can be removed and sent back using the original shipping box and packing materials.

20 deg C at -20 deg C Voltage (VDC) Fig. 7.1.1 Example representative ~100W PV module voltage – current characteristic at various cell temperatures Because PV modules also have a reduction in voltage at high cell temperatures, you must make sure the MPP voltage of the strings will not drop below the minimum inverter DC input voltage of 230V DC in very hot temperature conditions, including wire losses and voltage drop in order to avoid reduced system performance. Both the maximum open circuit voltage (OCV) when at cold extreme and minimum MPP voltage when at hot extreme can be calculated for a PV module using its specification sheet. Solectria Renewables’ online PV module string sizing tool can then be used to determine how many modules can be used in a string. 66 ...
